Melt spinning device

Abstract

A melt spinning device produces a plurality of multi-filament threads which includes a spinning apparatus, a cooling apparatus, a drawing apparatus and a winding apparatus. The drawing apparatus has a plurality of godet units entwined by threads, each of said units having a plurality of godets, which are axially rectified to a coil spindle of the winding device. The transition of the threads as yarn from the drawing device to the winding device is executed by a guide godet which is aligned axially crosswise to the godets of the godet units and under the drawing device, so that the threads can be guided by simple partial wrapping after rotation of the thread running plane of the yarn by 90°.

1 . Melt spinning apparatus for the production of multiple multifilament yarns, comprising:
 a spinning device including multiple spinnerets for extrusion of the yarns, disposed in a row,   a cooling device,   a drawing device including at least multiple godet units having multiple godets, around which the yarns are looped,   a windup device including multiple winding locations parallel to a spool spindle, and   at least one guide godet which is disposed between the drawing device and the windup device,   wherein the godets of the godet units and the spool spindle of the windup device are axially oriented in the same direction, and   wherein the guide godet is oriented transverse to the godets of the godet unit, underneath the drawing device, in such a manner that during a transition, the yarns can be guided on the guide godet after a rotation of the yarn run plane of the yarn web by 90°, with a single partial loop.   
     
     
         2 . Melt spinning apparatus according to  claim 1 , wherein the guide godet is disposed above the spool spindle, on the side, next to the winding locations. 
     
     
         3 . Melt spinning apparatus according to  claim 1 , wherein the guide godet has a second guide godet, oriented in the same way, assigned to it, above the spool spindle, which is disposed on the side, next to the winding locations. 
     
     
         4 . Melt spinning apparatus according to  claim 3 , wherein a swirling device is disposed between the two guide godets. 
     
     
         5 . Melt spinning apparatus according to  claim 1 , wherein the windup device is formed by two spool-up apparatuses disposed next to one another, each having multiple winding locations, and that the guide godet is disposed in the center, above the spool-up apparatuses. 
     
     
         6 . Melt spinning apparatus according to  claim 1 , wherein multiple deflection rolls that are disposed directly ahead of a changing device, in each instance, in the winding locations, are provided between the guide godet and the winding locations. 
     
     
         7 . Melt spinning apparatus according to  claim 1 , wherein a guide means that brings about a change in the yarn run plane of the yarn web about an angle in the range of 90° is provided between the guide godet and the last godet of the drawing device. 
     
     
         8 . Melt spinning apparatus according to  claim 1 , wherein the spinnerets are configured as a double spinneret, in each instance, by means of which two multifilament yarns can be extruded per double spinneret. 
     
     
         9 . Melt spinning apparatus according to  claim 8 , wherein the row of spinnerets is oriented transverse to the axes of the godet units of the drawing device and that at least one guide means is provided between the spinnerets and the drawing device, by means of which a change in the yarn run plane of the yarn web by an angle in the range of 90° is brought about. 
     
     
         10 . Melt spinning apparatus according to  claim 1 , wherein the cooling device has multiple cooling cylinders having a gas-permeable cylinder wall, which cylinders are held within a blowing chamber. 
     
     
         11 . Melt spinning apparatus according to  claim 10 , wherein each of the spinnerets has a respective cooling cylinder, and wherein the cooling cylinders are divided into two separate cooling zones.
